InequalitiesThe coordinate plane is a two-dimensional surface on which we can plot points, lines and curves. It has two scales, called the x-axis and y-axis, at right angles to each other that meet at the point of origin (0, 0). In this module, students use the concept of Formula M racing to understand the concept of inequalities. What does it mean if a solid line is found on the plane and all areas below the line are shaded? This could mean that anything on the line is a tie in the race and anything in the shaded area would be a loss. In other words, we’re looking at real-life activities to teach this abstract concept.
